1.3 Neurons & Neural Firing

Front

neurons

Back

Individual cells in the nervous system that receive, integrate, and transmit information.

Front

nerves

Back

Bundles of neuron axons.

Front

glial cells

Back

Provide nutrition and protection for the neurons.

Front

sensory neurons

Back

Take input received through sensory receptors throughout the body, pass it toward the brain and spinal cord to initiate a response.

Front

motor neurons

Back

Transmit signals away from the brain and spinal cord to our muscles and other organs.

Front

interneurons

Back

Relay neurons, or connects, allowing for information to pass between neurons within the brain and spinal cord.

Front

reflex arc

Back

Occurs when a signal is sent from a sensory organ to the spinal cord, which processes the information instead of passing it on the brain.

Front

reflex

Back

A simple, automatic response to a sensory stimulus, such as the knee-jerk response.

Front

dendrite

Back

Receive signals from other cells.

Front

axon

Back

Messages from soma travel down.
